Subcutaneous lump after surgery?
Due to a subcutaneous tumor in the thigh, surgery was performed on February 4th for excision.
Afterward, during a follow-up appointment to discuss the pathology report, it was confirmed to be a nodular fasciitis measuring 2x1.2x0.9 cm.
It has been 24 days since the surgery, and I recently noticed a hard lump under the skin at the site of the sutured wound.
The lump feels quite firm but is not very painful, and it roughly covers the entire wound area.
Is this normal, doctor? I am worried that the surgery may not have completely removed the tumor or that it might have regrown.
What could this hard lump be?

Hello: After the surgery, it is normal for the wound to be firmer, but it should soften after three months.

More Info
After undergoing surgery for a subcutaneous lump, it is not uncommon to experience some post-operative changes, including the formation of hard lumps at the surgical site. In your case, you mentioned that you had a surgical excision for a nodular fasciitis, and now, 24 days post-operation, you have noticed a hard lump at the incision site.
Firstly, it is essential to understand that the formation of a hard lump under the skin after surgery can be attributed to several factors. One common reason is the presence of scar tissue, which is a natural part of the healing process. When the body undergoes surgery, it initiates a healing response that involves the formation of collagen fibers to repair the incision. This scar tissue can sometimes feel firm or hard, especially in the early stages of healing.
Another possibility is the accumulation of fluid, known as a seroma, which can occur after surgical procedures. A seroma is a pocket of clear fluid that can develop in the space left by the surgery. While seromas are generally not harmful, they can create a palpable lump under the skin.
In some cases, the hard lump could also be related to inflammation or a localized reaction to the sutures used during the surgery. If the sutures are non-absorbable, they can sometimes cause a foreign body reaction, leading to localized swelling and hardness.
It is also important to consider the possibility of recurrence of the original condition, although this is less common shortly after surgery. Nodular fasciitis is typically a benign condition, and while it can recur, it is usually not aggressive.
Given your concerns about whether the surgery was thorough or if the tumor has returned, it is crucial to follow up with your surgeon. They can perform a physical examination and may recommend imaging studies, such as an ultrasound, to assess the lump further. This will help determine whether it is scar tissue, a seroma, or something that requires further investigation.
In summary, while the presence of a hard lump at the surgical site can be concerning, it is often a normal part of the healing process. However, it is always best to consult with your healthcare provider to ensure that everything is healing as expected and to address any concerns you may have about the lump. Regular follow-up appointments are essential to monitor your recovery and to catch any potential issues early on.
